PURPOSE:To output an actual angular velocity under any circumstances where a sensor is placed by introducing a correction term to an output signal of a twist detecting means when a signal output from a vehicle velocity detecting means corresponds to that when the vehicle velocity is zero. CONSTITUTION:A present output value R2 of a twist detector 3 is input to an operational circuit 15, and also a signal R3 corresponding to the present vehicle velocity is input thereto from a vehicle velocity sensor 16. When the signal R3 is corresponding to a value when the vehicle velocity is zero, the signal R2 output form the detector 3 is compared with the value of R1 stored in the circuit 15. When R1<R2, R2-R1 (error) is operated in the circuit 15 and the resultant value R4 is stored in the circuit 15. Thereafter, a value obtained by subtracting R4 from R2 is output from the detector 3. On the other hand, when R1>R2, an operation R1-R2 is performed in the circuit 15, the result of which is stored in the circuit 15 as R4. Then, a value obtained by adding R4 to R2 is output as a corrected output of the detector 3. |
